To all whom t may concern Be it knownthat I, WILLIAM W. QUTNTON,

citizen ofthe United States', residing at Nortlibrid e, in the county of Worcester and State of Looms, lof which the following description, in connection with the accompanying drawings, is a specification, like characters on the I relates tofeeler inechzfnisms'forlooms, andv more particularly to the detecting end of drawings representing like parts.

The invention to be hereinafter described the feelermembers of such mechanisms'.

In .that type of feeler mechanisms where the feeler member is moved longitudinally 'of the shuttle at the critical point of eX- haustion, `the feeler member is usually provided with a toothed or serrated end which,

by engagementJ with a working supply of filling in the shuttle, prevents Imovement of the feeler member longitudinally of the shuttle, but when'the filling has become substantiallyl exhausted, such toothed or ser- 25l rated portion is permitted to move longitudinally along the filling carrier or bobbin and initiate filling replenishment. In feeler motions of this'type, the feeler member must be sensitive to either the presence or substantial absence of filling in the shuttle, and

fin the latter event, 'its movement longi-' tudinally of the shuttle must be effected lpromptly upon detection of substantial eX- lhaustion. i

An important feature of the present injvention, therefore, consists of a feeler member, the detecting end of which will make nown either the presence or substantial eilaustion of the filling in the shuttle, and 1n the lattereV'ent, will facilitate movement of thefeeler memberin a direction longitudinally of theshuttle.v .Incarrying this fealture of the invention into'effect, the detecting or rear end of the feeler-member is -provided -with a toothed portion for engage#- -`mentl with the filling, anda'relatively movable .part or-roller which, when the filling is substantially exhausted, will .facilitate moveing'end of which is formed of a metallic and non-metallic portion, the former'hmom assachusetts, have invented an Improvement in Feeler Mechanisms for ing ineffective when the filling reaches apre-l determined degree of'eXhaustion, thereby allowing the non-metallic member to contact with the filling or carrierin the shuttle to control the movement ofthe feeler member.

The-above and various other features of the invention will best be made clear from the following description and accompany# Figure l is a side elevation of aportion of a feeler member embodying the present invention;

Fig, Q'is a view similar to Fig.` 1, with the detecting or rear end of the feeler member shown in section on the 4line 2--2, Fig. 3;

Fig. 3 is a View looking at the detecting end of the feeler member;

Fig. 4 is a section on the line L1--4 of Fig. 1;

Fig. 5 'is an enlarged view/showing the general action of the feeler member during lthe presence of a working supply of filling in theshuttle on a detecting beat; and

Fig. 6 is a cross-sectional View through the filling carrier or bobbin showing the action of the feeler member when ythe filling is substantially exhausted. E

The 'present invention is more especially directed to the detectingor rear end of the yfee-ler member of the so-called side swipe7 feeler, wherein the feeler member is moved longitudinally of the shuttle on a detecting beat when the filling is substantially-exhausted, to thereby initiate filling replenish. ment, and while adapted. for advantageous' use in connection with the side swipe form of feeler mechanism, is, nevertheless, capable of advantageous use in connection with other types of feeler motions. I nasmuch as the present invention relates solely to the de- .tecting "or rear end portion of the feeler member, only/s0 much of the feeler mechanismis shown and described as appears necessary for a proper understanding of the construction 'and inodeofoperation of the -invention itself. v

In the drawings: The feeler 1 may be of anyvusual type. of the feeler member 1 may be variously associated wit-h the'feeler member itself, but in the present instance, the detecting or rear 0116132 of. the-.feeler member is shown as a The detecting or rear end part made separate from' and secured to the i feeler member. This, of course, inay be otherwise contrived.

The detecting end 2 of the feeler member is slotted as at 3, thereby forming the side portions 4 which are -provided with a toothed part 5 for engagement with the tillingon a detecting beat. The side portions 4,

. 4, substantially as indicated in Figs. 3 and 4. The roller 6 has its peripheral edge portion extending slightly rearwardly or beyoud the toothed portion 5 of the feeler end,

substantially as indicated in Figs. 1 and 2,

A 'the construction being such -that upon a deiberoid, or similar substance.l i

lVlienthe feelei" member is in vfeeling position, substantially asV indicated-in Fig. 5,

f, ,working supply of filling 11 on a" detecting tectingbeat the peripheral portion of the roller 6 will -sink in to the filling and permit the teeth 5 of the' metallic side' portions 4 to engage and be held by the filling. i

Disposed between the vside .portions 4 of..

the'detecting end vof the feelermember is a non-metallicpportion or member which f may be provided with teeth 9 corresponding tothe teeth 5 of the side portions'f't.v The non-metallic member 8 may be vformed Yof and the fillingcari'iei' 10'is provided with a hcatytheroller 6 will4 sink 'intoftlie filling and permit the metallic toothed portionv at' v each side of the'non-metalli(` toothed portion 8 tov engage the mass offilling and hold y the fe'elei member from movement lm'igitii-'f dinallv of the shuttle, As tlieeliameter of the filling carrier becoii'ies less andless.' its cylindrical surface will presentlessand less area for engagement .by the teeth5fof the metallic/portion of the detect-ing end 'of the 'feeler until. when a ifedete'rmined deffree of exhaustion of filling has'be'eii reached. as indicated graphically b'v-Fig. 6. themetallic toothed portion' 5 of the detecting end of thel feeler will"`no longer engage the few coils of remaining filling or the filling carrier, but tlies'e'willbethen engaged by the teeth 9 of the inteiinediate'lion-metallic portion 8. 4'The'teeth 910i the iinanetallic p or-v tion 8 will then control the movement vofthe feeler inembeiga/nd when the filling has become substantially exhausted. 'and thel roller 6 no longerinks sii'eiently 'fai'.into the fill- -xof the shuttle to ing to permit. iti-:f engagement by the teeth 9, the feelermember will move longitudinally lVhen the filling is-subst'antally exhausted@ as indicated in Fig. 6, the peripheral portion.

of the roller-.Gland the non-metallic teeth 9 will alone engage the filling or the filling" cai'rier and, owing to the character of these parts, will :riot injure the filling carrier or bobbin. s i

-The abovecdescribed construction has been found especially advantageous Awhen used with coarseor soft yarn, although it may be employed with advantage in the finer and harder spun yarn.
